I have a used ProMariner ProSport20 for sale. It has two banks and will charge all but lithium (well it has no lithium setting anyway). It has been and still is a great onboard charger.

I purchased lithium batteries and got a lithium specific charger so I no longer need this one.

I have an ad on Kalamazoo CL in the boat parts section with contact information.

I don’t constantly check my pm’s but will make an effort to do so while the ad is up. Sorry no shipping, local pick up only or I might meet somewhere if it is convenient for me.
